Traboules
Traboules are passages inside old buildings, between parallel streets, made to easy the transport of silk and other goods. We can find them on the old Lyon and Croix Rousse. They are quite dungeon-like and sometimes creepy, with a small interior yard where you can see the sky. These are mostly private areas, but most are open (just push the door to enter), you have to know them though, because they look like normal house doors from the street…
Traboules are, allegedly, one of the reason that occupying Nazis couldn’t take complete control of Lyon during World War II, you could, in fact, easily hide a small army in there.
